' AUTOMATIC RECORDING APPARATUS FOR LONG SAWS OR SIMILAR MACHINES.

Specification of Letters Patent.

Appliiaation filed December 20, 1910. Serial No. 598,374.,

To all whom it may concern:

Be it known that I, GUSTAF EMANUEL JOHANSON, a citizen of the Kingdom of Sweden, residing at Sundsvall, Sweden, have invented new and useful Improvements in Automatic Recording Apparatus for Long Saws or Similar Machines, ofwhich' the following is a specification. I

This invention relates to automatic recording apparatus for long saws or similar machines.

The object of the invention is to construct a recording apparatus which is capable of recording all works made in long saws or similar machines in such a manner that the records show directly or may be used as a base for the calculation of the wages due to the Workman independently of whether the cutting works made during the period of payment have been ofone and the same kind or of different kinds for which various wages are to be paid. I

A further object of the invention is to construct the apparatus insuch a manner that it can record independently of the chiciency of the machine on which it is applied the wages due to the workman on account of one and the same principal agreement for i all machines.

The invention more particularly relates to such recording apparatus as are drlven by the deal or the like passing through the machine by means of a roller bearing against and rotated by said deal or the like, and the invention consists principally in that said roller is divided transversely in a number of parts corresponding to the number of the feed speeds of the machine or to the number of classes of width of wood for which according to the agreement difierent wages are to be paid, said parts of the roller being rotatable independently of each other and by means of a variable speed gearing connected with a' common recording roller.

In the accompanying drawings I have shown diagrammatically some embodiments of my invention. I

Figure 1 shows a plan-view of one embodiment of the invention and Fig. 2 a section on line AB of Fig. 1. Fig. 3 shows a plan-view of a second construction form 600 minntes=10 hours. Fig. 4 is a section on line C- -D of Fig. 3. Fig. 5 shows a section on line G-H of Fig. 3, and Fig. 6 shows a section on line E-F of Fig. 3. Fig. 7 shows a third construction form in plan-view and Fig. 8 shows a side view of some details of this form.

The driving member of the apparatus consists of a roler bearing against the deal or the like passin 'through the machine and being rotated y said deal or the like. Said roller may be provided specially for the purpose in question or one of the feed rollers of the machine, hereinafter referred to as the long saw, may constitute said driving roller being for this purpose freely rotatable. According to my present invention said driving roller is divided transversely in two or more, for instance three, parts 1,2 and 3, whichare rotatable independently of each other on a fixed shaft 4, or each of said parts may be secured to a'sepa- Patented Sept. 10, 1912. i

rate rotatable shaft. The roller parts 1, 2 and 3 are provided at such a distance from each other that only the lowermost part 1 is operated by deals of the smallest width, while deals of the next higher class of width operate also the intermediate roller part 2 and the widest deals operate all three roller parts. To each roller part is secured a toothed wheel 5, 6 and 7 respectively. Said toothed wheels may be of different sizes, as is shown in the drawing where the uppermost wheel 7 is the largest'one and the lowermost wheel 5 the smallest one. Each toothed wheel 5, 6 and 7 engages a toothed wheel 8, 9 and 10 respectively, rotatably mounted on an axle 11. Each toothed wheel 8, 9 and 10 is provided with a pawl 12 engaging a ratchet wheel 13, H and 15, rigidly secured to the axle 11. On the latter are .further provided three toothed wheels 16,

17, 18 0 different sizes, each of which is adapted to engage a toothed wheel 19,20 and 21 respectively of "different sizes and rigidly secured to a sleeve 22 which is slidably but non-rotatably connected to an axle 23. Said sleeve 22 is by means of any suitable dcvice (indicated in Fig. 2 by a lever 24) connected to the belt fork by means of which the driving belt of the long saw for obtaining different feed speeds is moved on the step pulleys of the saw, the connection between the sleeve Y22 and the belt fork being such that the toothed wheel 19 is in engagement with the toothed wheel. 16 whenthe driving belt of the saw adjusted for the highest feed speed.

The toothed wheels 19, and 21 are so arranged in relation to the toothed wheels 16, 17 and 18 that only one pair of these toothed Wheels are in engagement with each other in the. different positlons of the sleeve 22. On the axle 23 is provided a screw m which engages a screw wheel 26 on an axle 27 on which is mounted a recording roller 28. On the latter is placed a paper strip or the like (not shown) having a scale corresponding to dollars and cents or any other kind of coin. Against said paper strip bears a writing pin 29. If the roller itself is provided with said scale, a pointer may be substituted for said writing pin, as is easily understood. It will also be understood that one may arrange the recording roller fixed and have the writing pin or pointer rotate around the roller, if desired. The whole apparatus may be inclosed in a suitable casin (not shown) in order to prevent unallowe access to its parts, and the recording roller may suitably be arranged in such a mannerthat it is visible to the workman so that the latter may at any time control the amount of his wages.

The apparatus described above works as follows: When the saw has been adjusted for the highest feed speed and thetoothed wheels 16 and 19 are in engagementwith each other and a deal of the class of deals of the smallest width is introduced between the feed rollers 31, 32 of the saw and strikes the lowermost roller part 1, the latter is put in rotation and drives by means of the toothed wheels 5 and 8, the pawl 12, and the ratchet wheel 13 the axle 11 which in its turn by means of the toothed wheels -16 and 19, the sleeve 22, the axle 23, the screw 25, the screw wheel 26 and the axle 27 drives the recording roller at a speed at which the writing pin 28 records the determined wages. When the long saw is adjusted for the next lower feed speed for cutting deals of the next higher class of width, which actuate both the roller part 1 and the roller part 2 the sleeve 22 is so displaced that the toothed wheels 17 and 20 come intoengagement with each other. When now a deal of the last mentioned class of width passes through the long saw, the axle 11 is driven from the 65 roller part- 2, the toothed wheels 6 and 8 being larger than the toothed wheels 5 and 9 respectively. The pawl 12 of the toothed wheel 8 in this case slides on the teeth of the ratchet wheel 13. Further the toothed 60' wheels 17 and 19 are larger than the toothed wheels 16 and-20 respectwely, and the whole gearing between the roller part 2 and the recording roller may be such that on the latter or on the paper strip thereon are re- 65 corded either the'same wages per unit of time of the actual runningl of the long saw as in cutting deals at the ighest feed speed or any other wages according to agreement. Also the gearing between the recording roller 28 and the roller part 3, which latter is put in operation by deals of the highest class of width which as a rule passes through the long saw at the lowest feed speed, may be such that on the recording roller are recorded either the same wages per unit of time of the actual running of the long saw as in cutting deals at the other feed speeds, or any other wages as the agreement may be. It may be understood that for the gearings shown-in the drawin any other gearings of arbitrary or suitab e kind may be substituted. In order that theapparatus may be adjusted for variations of the groups of width in which the deals are classified, the roller parts 1, 2 and 3 may be adjustable longitudinally in relation to eachother. The sleeve 22 may be locked in itsvarious positions by any arbitrary or suitable means.

Figs. 3-6 show a recording apparatus having two recording rollers. On the one of these rollers the wages are recorded and the parts driving this roller are for the sake of clearness indicated by the same reference characters as the corresponding parts in Figs. 1 and 2. On the other roller the actual running of the long saw is recorded in percentage of the nominal running. Such a record is of great importance as it enables the superintendent to udge to what an extent the elficiency of the machines is utilized, and it is also a stimulus for the workman to increase the intensity of his work, inasmuch as in the most cases a premium or reward above the usual wages is paid when the actual running of the machine counted in time surpasses a certain percentage of the nominal running. The. actual running is,

as well known, shorter than the nominal one as always acertain time is required for inspecting the machine, lubricating, repairing belts and so on. The device for driving the last-mentioned recording roller 33 is in the form shown the following. To the roller part 1, Fig. 4 (or to a special roller actuated by all deals) is rigidly secured a toothed wheel 34 engaging a toothed wheel 35 rotatably mounted on theaxle 11. To said toothed wheel 35 is rigidly secured a toothed wheel 36 engaging a toothed wheel 37- on an axle 38. The latter supports as the axle 11 a number oftoothed wheels 39, 40 and 41 of diiferent sizes, corresponding to the number of feed speeds of the long saw and each being adapted to engage a toothed wheel 42, 43 and 44 respectively (Fig. 5) on an axle 45, the last-mentioned wheels being adjustable longitudinally on the shaft 45 for instance by being mounted on a sleeve 46 slidable on said shaft, and connected to the same by key and key way or the like so that the corresponding toothed wheel on the shaft 38 in each position of the sleeve 46.

Theshaft 41 is by means of any arbitraryor suitable gearing for instance a screw 47 and a screw wheel 48 connected with the axle 39 of the recording roller 33. The toothed wheel gearings 39, 42, 40, 43 and 41, 44 are so chosen that they at the corresponding feed speeds of the long saw give one and the same speed to the axle 45 or to the recording roller 33 so that on the latter independently of the feed speed of the long saw the actual running of the latter is're corded in hours and minutes. Of course, this record will not be fully exact per unit of time on account of variations in the running of the driving motor, slippin of the belts and so on, but yet it will be sufficiently exact for its purpose. The sleeve 46 may as the sleeve 22 suitably be. displacedby means of the belt fork by means of'which the driving belt is adjusted on the step pulleys of the long saw or by means of any'other device serving to change the feed speed of the saw. Fig. 6 illustrates by way of an example how the sleeves 22 and 46 may be combined with the said belt fork. The latter, which is indicated by 50, is at the one end formed as a rack in which engages a toothed wheel 51 to which is rigidly secured a.

toothed wheel 52 engaging a rack 53. The latter is provided with a cross-piece 54 each end of which engages one of the sleeves 22 and 46 in such a manner that thelatter are compelled to partake in the movement of the cross-piece but are not prevented from rotating. The gearing between the rack 53 and'the belt fork 50 is such that the sleeves 22 and 46 are adjusted in the desired positions'when the belt fork is displaced.

In cases where the wages for the various feed speeds or for cutting deals of the various classes of width are one and the same counted per unit of time and the gearings between the roller parts 1, 2 and 3 thus should give one and the same speed to the recording roller 28, the writing pin of this roller obviously may record not only the wages but also the actual running of the long saw in percentage of the nominal one indicated in hours and minutes. In this case the recording roller 33 and its drivmg mechanism are dispensable.

hen an apparatus according to the present invention is to be used 1n a lon saw the feed. rollers of which are'adjustable to and from each other, also the roller parts 1, 2 and 3 must be adjustable in the same manner and in the same degree as the .feed rollers. A form of this device is shown in Figs. 7 and 8. The shaft 4 supporting 1 frame 55 of the machine in a direction at right angles to the direction of movement of the deals, and this sliding piece supports also the axles l1 and 38, though this is not shown on the drawing.- The said sliding piece '56 also su ports hearings (not shown) for axles 57 an 58.- All other parts of the apparatus are mounted on the frame 55 of the machine. The axles 57 and 58 are by means of screw gearings 59, 60 and 61, 62 respectivel connected to the axles 11 and 38 respectively. ,Further the axles 57 and 58 by means of keys and key ways or any other similar device are in engagement wit hollow axles 63 and 64 respectively, in which they are slidable and which support the above described toothed wheels 16, 17, 18

and 39, 40, 41 respectively. The axles 23 and 45,. which support the above described toothed wheels 19, 20, 21 and 42, 43, 44 re spectively by means of the longitudinally slidable sleeves 22 and 46 respectively, are each connected to one of the recording rollers 28 and 33 by means of a bevel wheel 1 gearing 65 and 66 respectively. The sliding movement of said sleeves is effected by means of a similar device as that shown 1n .Fig. 6. When the sliding piece 56 is "displaced the axles 57 and 58 are moved longitudinally in the hollow axles 63 and 64,

this movement being without influence on the function of the apparatus. Instead of mounting some parts of the apparatus on the said sliding pieceand the other parts on the frame of the machine one may, as will be easily understood, mount the whole apparatus on said sliding piece or on any other part of the machine corresponding thereto.
